Connection Reset By Peer: Server v1.1.6 - Client v1.4

[CuSo4]

Hello, I have a Zabbix server (version 1.1.6) running, and 7 Zabbix clients (version 1.1.6). When I try to add a new client (version 1.4), I get a "Connection reset by peer"-error.

The server log says:

... Timeout while receiving data from [Hostname]
... Connection reset by peer.
... Host [Hostname] will be checked after 60 seconds

I've tried both in active and passive mode.

The client log in active mode says:

... zabbix_agentd started. ZABBIX 1.4.
... zabbix_agentd collector started
... zabbix_agentd active check started [serverhostname:10051]

The client log in passive mode says:

... zabbix_agentd started. ZABBIX 1.4.
... zabbix_agentd collector started

When I telnet from the server to the client I get:
# telnet clienthostname 10050
Trying x.x.x.x...
Connected to clienthostname
Escape character is '^]' .

but there isn't any reaction after that. (I tried typing "version[zabbix_agentd]")


When I telnet from the server to the client I get:
# telnet serverhostname 10051
Trying x.x.x.y...
Connected to serverhostname
Escape character is '^]'.
QUIT
Connection closed by foreign host.

I have added the client & server configuration files as attachment.

Does anyone has any suggestions about how to solve this problem?
Thanks in advance!

I have seen this same problem in my environment, and it has been caused every time by the agent machine not having a route back to the zabbix server. Add a route and fix the problem!

Thanks for your reply!
However, I checked the routes, and everything seems to be fine.
I have another client on the same vlan that works correcty.
Furthermore, I can ping and ssh from server to client, which should also rule out a routing configuration error...
